Quantum Computing and Blockchain in Business

By: Arunkumar Krishnakumar

Overview of this book

Are quantum computing and Blockchain on a collision course or will they be the most important trends of this decade to disrupt industries and life as we know it? Fintech veteran and venture capitalist Arunkumar Krishnakumar cuts through the hype to bring us a first-hand look into how quantum computing and Blockchain together are redefining industries, including fintech, healthcare, and research. Through a series of interviews with domain experts, he also explores these technologies’ potential to transform national and global governance and policies – from how elections are conducted and how smart cities can be designed and optimized for the environment, to what cyberwarfare enabled by quantum cryptography might look like. In doing so, he also highlights challenges that these technologies have to overcome to go mainstream. Quantum Computing and Blockchain in Business explores the potential changes that quantum computing and Blockchain might bring about in the real world. After expanding on the key concepts and techniques, such as applied cryptography, qubits, and digital annealing, that underpin quantum computing and Blockchain, the book dives into how major industries will be impacted by these technologies. Lastly, we consider how the two technologies may come together in a complimentary way.

Interview with Sam McArdle, Quantum Computing Researcher at the University of Oxford

In several previous chapters of this book, I have touched upon the barriers for quantum computing to go mainstream. One of the major barriers with quantum computing is the challenges with error correction. In a classical computer, bits have two states, "0" and "1." Therefore, error correction is a lot easier. In a quantum computer, qubits can exist in superpositions at any point in time during the calculation. As a result, it is harder to observe and correct their values without disrupting the calculation.

Error correction within quantum computing is a fascinating space and there are several techniques being explored. Hence, I wanted to dedicate one interview, and thus a chapter, to this topic. I met Sam McArdle at a quantum computing event at the University of Bristol. He made a presentation at the event on his research at the University of Oxford. The research focused...
